It's heavily hinted that the Eds in general have abusive parents. Eddy's parents don't seem to care that his brother beats him up and basically treats him like garbage. Edd probably has the least abusive because while his parents are seldom around, they communicate with him through sticky notes (some of which have personal advice written on them) and give him warm milk and massages before he goes to bed, which hint that when they ARE around, they try to be good parents.
Though he is never actually seen, Eddy's brother is strongly implied to be this... only for the movie to reveal that he's actually a sadistic bully who enjoys beating up Eddy for kicks, and that Eddy made up everything he said about him...
Kevin also qualifies, being the cool athletic kid. A good example is the episode "This Won't Hurt an Ed".
Achievements in Ignorance: Ed's lack of intelligence can allow him to do the physically impossible, such as in Will Work For Ed when he puts his work boots on facing backwards, and in The Call Him Mr. Ed when he builds a tower of miscellaneous junk all the way up to the moon.
Adorably Precocious Child: Edd fits the bill somewhat. While being the most mature of the bunch, he does have a childish fondness for jawbreakers like everyone else.
Aerith and Bob: All characters have very common names (Jimmy, Jonny, Kevin, Sarah etc.) But then there's Nazz, which isn't as common. It's justified in Rolf's case because he's not originally from Peach Creek and is implied to be originally from somewhere in Europe.
All too often, Eddy's antics will net Ed and Edd the same punishment/retribution, no matter if they were unwitting accessories or if they tried to stop him. This is a major reason why some fans don't like the other kids.
Averted in "Brother, Can You Spare an Ed?", where Eddy is the only one punished while Ed and Edd were completely repentant about what happenednote Eddy wheedled Ed into spending Sarah's candy money on himself and promised to pay Sarah back. They did suffer some abuse from Eddy, but in the end he got the brunt of it.
And again in "A Case of Ed" when Edd gets Kevin to beat up the other two for teasing them both.
Zig-zagged in "Pain in the Ed", where Eddy caused all the problems while Ed and Edd were innocent. Ed got away, Edd got beat up a little, and Eddy got the worst of it.
Rolf, but it's possible that his skin is tanned from all the farm work he does outside.
Ambiguous Disorder: Ed and Edd. Ed could range anywhere from just being a bizarre combination of eccentric and slow for his age to a full on case of mental retardation. Edd definitely has some form of OCD, but who's to say exactly how severe it is or if it's the cause of his signature social anxiety rather than some other problem.
Ambition Is Evil: The source of Eddy's bad luck. Inherited from his scheming brother.
Lampshaded in the movie with Eddy commenting that he is getting tired of slapstick after getting injured yet again. They receive no more injuries before Eddy's brother comes out. See below.
Notably, in the movie, the kids who fell for the Noodle Incident scam end up keeping their injuries for the first portion. It still didn't wear them down a bit, which is concerning considering Rolf was missing large chunks of flesh, and Jonny had a Bear Trap clamped onto his head.
Subverted later in the movie, in that Eddy being beaten up by his brother is treated very seriously and the cul-de-sac kids witnessing this and Eddy's subsequent breakdown leads them to finally forgiving and accepting the Eds as their friends.
Jimmy gets horribly injured several times each show, yet is still able to speak and think competently.
Animation Bump: This was the very last animated series to be made with painted cels. After season 4, the show switched to digital ink and paint, resulting in a brighter color scheme and tighter linework.
Ed: The school will tell Sarah, and Sarah will go tell Mom, and Mom will go tell Dad, and Dad will just SIT THERE AND WATCH TV!
Ed: It's Sarah! We are so doomed! Help me, guys! She'll tell Mom and Mom will tell Dad and he'll say "Not now, I just got home from work!"
Art Evolution: Early on in the series, the characters looked somewhat less human (notably, their jaw shapes being more exaggerated) and the color scheme was duller. The lines were also somewhat less thin and wriggled a bit less, as well. The characters are also quite bland, compared to their later portrayals.
The animation also seemed alot more restricted and understated in the first few seasons. Compare a season 1 episode to a season 5 episode, and the animation style is far more exaggerated and 'wacky.'
Ed's appearance actually got a little less realistic compared to the other kids after the first season, becoming less Gonk-ish and gaining more stylized facial features. He also develops an amusingly weird quirk in later seasons where one of his eyes would float independently of his head when he got really excited.
Author Avatar: The Ed's personalities were actually based on the personality traits of the show's creator, Danny Antonucci.
Aww, Look! They Really Do Love Each Other: Ed's always shown to genuinely care about Sarah despite the abuse she dishes out to him, but it's been shown a few time that deep down, Sarah does genuinely care about her brother; she only gets to an eye-rolling exasperation with Ed, and Ed will always obey Sarah's requests.
Bad Mood as an Excuse: In "Little Ed Blue", Ed gains a bad mood, becoming aloof, violent and outright intimidating to everyone, even Sarah. This is stopped when Jonny pulls off his shoe, revealing a pebble inside, and Ed is blissful again.
Bait and Switch: In "A Town Called Ed", it clearly seems a row of lockers will fall on Eddy. They don't.
Bamboo Technology: Edd's scrap-made inventions. He makes whole cities and theme parks out of cardboard—and they may or may not work.
Banana Peel: Kevin slips on a banana peel in the episode "See No Ed".
Attempted and failed in the opening of one episode, where Eddy runs up to Jonny and orders him to start doing random things seemingly as part of a game (such as catapulting marshmallows into a tuba or popping the balloons holding Ed aloft). When he gets to "Put a quarter in the jar, quick!", Jonny says "Nice try, Eddy." and walks off.
Used more successfully in an earlier episode where the Eds want to steal Jonny's spot at the swimming hole. While Eddy plots, Edd just pulls out a whistle and blows, causing Jonny to jump up and dive as if he were trying out for swim team.
Bee Afraid: The Eds start a beehive extermination business in one episode. It doesn't end well.
Behind a Stick: "Three Squares and an Ed" offers us a rare variant by showing us the view from behind the impossibly thin hiding place.
Jimmy has planned up schemes so brilliant that even Eddy considered them to be too diabolical. Jimmy also beat the living mess out of Edd and left him with his finger tied to his arm and his leg tied to his...other leg. He bit a chunk out of Edd's tongue.
Edd himself proved to be just as dangerous anytime he has an emotional meltdown. He also appears to be much stronger than he normally lets on since he's able to KO some of the strongest kids in the show with accidental, clumsy strikes that if done by anyone else would like a slap on the wrist or gentle tap.
Sarah: Ed! You can't throw me out, I live here too! Ed: SO MOVE!!!
Nazz falls into this category so many times.
Don't piss off Plank. He has back-up. Assuming that Plank is in fact just another facet of Jonny's personality, it shows that underneath Jonny's happy-go-lucky exterior is a kid who will mess you up if you cross him.
Rolf is arguably the friendliest of the cul-de-sac children, and he's not someone to be trifled with either, if you don't want to have a four-foot fish smack into your face....or something worse then that.
May Kanker, being the nicest (or, at the very least, the least mean) of the Kankers, falls into this.
"X Marks the Ed" - Rolf makes Eddy's zit disappear, but it ends up shrinking his head.
"Ed Overboard" - Edd and Eddy manage to save Ed from the Kankers with the Urban Rangers' help, but shortly after, the rangers take Ed away after they get covered in make-up.
"Run For Your Ed" - the Kankers actually leave the Eds alone, but the cul-de-sac is still in ruin, and Eddy gets his finger stuck in a faucet after the Eds hid in Edd's kitchen sink.
"The Good, The Bad, and the Ed" - Eddy loses the challenge to get The Hairy Chest of Resilience Badge, but he gets a badge as a consolation prize, although it's the embarrassing "Crybaby Boo-Hoo" Badge.
Which is really unfair given what he had to go through. It included jumping off a cliff and getting hit by a passing train as well as many other impossible/stupidly dangerous tasks.
"A Fistful of Ed" - Eddy loses all respect he's accumulated, but he manages to get the Kankers to go away.
"An Ed Too Many" - The Eds manage to get Jimmy and Sarah back together, making Sarah forget about her crush on Double D and thus getting her to leave them alone, but Eddy, blaming the Four-Leaf Clover they found at the beginning of the episode for the events, throws it away. It is subsequently found by Jonny, who has a sudden string of good fortune, much to Eddy's chagrin. Oh, and Ed's still hungry.
"Virt-Ed-Go"- The Ed's treehouse for their club scam is taken over by the Kanker Sisters, but the treehouse was poorly-made and looked like it could fall at any moment.
"Will Work for Ed" - Eddy forces Ed to work for Rolf, who's a Bad Boss. Edd manages to get them in good terms, and both him and Ed get Jawbreakers while Eddy has to work for himself. One of the few episodes that ends with the Eds getting what they want with minor damage overall and no scams needed for it.
"Brother, Can You Spare an Ed?" - Eddy spends the episode in Jerkass mode earning money out of Double D's and Ed's misery. By the end, Double D and Ed get sick of his bullshit and manage to repay everything he's done to everyone by using his own scam against him.
Blah Blah Blah: In the "Rashomon"-Style episode, how Ed remembers Double D's dialogue. Also, how the guys view Nazz while talking, because they're stunned by her beauty.
Blazing Inferno Hellfire Sauce: The "Honor Thy Ed" episode starts with the Eds having set up a taco stand selling "tacos" made of paper plates, grass, and shredded crayons. After Ed, Extreme Omnivore he is, eats several crayons thinking they are flavors, Edd humors him and takes a bite of one. He is disgusted and needs water, but the closest thing is Eddy's Brother's Armenian Secret Hot Sauce. He guzzles part of it and seems unfazed at first. Ed also consumes some. Eddy thinks the sauce didn't work and also eats some. It's at that moment the effect takes hold, however. We see a Discretion Shot from down the street as a tower of flame erupts from the stand and the Eds sticking their mouths on a sprinkler.
In addition, most fanarts of the Eds done in realistic or anime style tend to portray Edd as blonde, Eddy with black or blue hair, and Ed as a redhead. Ed being redheaded is technically canon since in one episode, when he combed his hair, it turned out to be red. That makes sense, as his sister Sarah's also a redhead.
Breaking the Fourth Wall: In a quite literal example, the trio ends up getting shot into the air, where they proceeded to crash into the sky from a viewpoint of them crashing into the television screen. The sky begins to shatter, revealing television snow behind it.
It's Way Ed, 1999: Edd: "In another ten years, we'll be back in style." The Movie, 2009: The Eds attain popularity with the other kids.
Stop, Look, and Ed: "I'll just save [the secret of what's under your hat] and use it for ammo when I need to, Double D." From Here to Ed: "How 'bout I blow the whistle on what's under that hat of yours, Double D?"
Bubble Pipe: When Nazz is babysitting at Eddy's house and he believes that it's a date. Edd notes it makes him look ridiculous.
While Ed is typically very stupid, he is incredibly resourceful/crafty in many situations in the series.
Eddy's plans would work if the rest of the cast weren't so Genre Savvy and/or terrible stokes of luck happened to smack them in the rear.
Butt Monkey: The show is one big universe of Butt Monkeys, regardless of whether or not they deserve it.
The Three Ed’s, almost everyone on the show hates them, they are constantly humiliated from their attempts to earn respect from their peers and doomed to fail at every money-making venture they've ever made. The one who brings it upon themself the most, however, is Eddy.
In a Brick Joke, Sarah serves Ed "buttered toast" and "gravy" for dinner when he's grounded.
Lampshaded in a Spin-the-Bottle/Truth or Dare episode, where they're forced to switch personalities. Edd, posing as Ed (obviously), says "gravy" and "buttered toast" all the time, causing Ed to protest that he doesn't say them that much.
Sarah often says "Wait until I get my hands on you!" whilst chasing someone. (Usually Ed.)
Cerebus Retcon: The series finale reveals that the reason Eddy is such a jerk is that all the years he endured with his big brother were in fact torture, and that pretty much everything he had ever said about his brother was made-up.
Chaos Architecture: The environment decides whether or not to grow steep hilltops in some episodes or if the alleys are big enough to support a cardboard city.
In addition, the Eds' theme park.
Characterization Marches On: The Eds in the later seasons are almost unrecognizable in personality compared to how they were earlier. Ed was presented as a slightly smarter, but more absentminded tweenager than outright stupid or infantile like he is later, and he initially lacked the Super Strength that became a major part of his character. Edd was also much more relaxed and low-speaking, and far more willing to go along with Eddy's scams—contrast to how neurotic he is later on, as well as being the "Moral Compass," so to speak, of the trio. Eddy in the early seasons wasn't the greedy, narrisictic, Jerkass with a Hair-Trigger Temper that we know in later ones.
Chekhov's Gunman: Eddy's brother has been occasionally mentioned in spite having no real relevance to the plot, except for a few moments. But later on, it appears as he's responsible for Eddy's entire character of being a greedy, narcissistic Jerkass, what with the way he brutally abuses Eddy in one of the most serious forms of Slapstick in the entire series.
Kevin is this to a lesser extent—Nazz is implied to have a crush on him and they get a lot of Ship Tease in the movie, and the Kankers, while they're obviously more into the Eds, consider Kevin attractive enough to want to kiss him.
Christmas Carolers: In "Fa La La La Ed", Ed brings the spirit of Christmas to the cul-de-sac, despite it being the middle of July, at one point, Eddy decides to use Ed's gimmick to his advantage by scamming other kids out of change by he, Ed and Double D caroling door-to-door, allowing him to buy them a large bag full of jawbreakers.
And Ed's lucky (and really stinky!) piece of cheese, Sheldon until Eddy chucked him into the creek.
Edd's cactus, named "Jim." He plays a minor role in A Glass of Warm Ed.
Continuity Nod: The show is positively loaded with these, the most being in The Movie. One example includes Ed getting shocked and getting into costumes and forms he had in several past episodes.
From the movie, upon Edd seemingly figuring out that Eddy's Brother has something to do with the Lemonbrook gag factory, Eddy references the mascot episode, "Tight End Ed".
"It Came From Outer Ed" has a cameo of the Masked Mumbler porta-potty booth from "Tag Yer Ed".
"The Good Ol' Ed" revolved around making a time capsule, which featured many devices from previous episodes, including the Eddo puppet from "Honor Thy Ed", the hypno-wheel from "Look Into My Eds", the Canadian Squirt Guns and hat from "Know It All Ed", the Fad Freak costume from "Its Way Ed", the ice pack from when they destroyed Jonny's house in "Rent-A-Ed", and the weapon fish from "Dueling Eds". It also references the rocket car from "Ready, Set, Ed!", the chain of deals from "Who, What, Where, Ed?", and the time they painted a spatula gold to pass it off as jewelry in "High Heeled Ed".
In "Out with the Old, In With The Ed", Johnny can be seen playing with the Whiz-Whaz toy from "Its Way Ed".
There's also Ed's sleepwalking in "A Glass Of Warm Ed", which comes back to explain how the Eds got the Kankers' ship-in-a-bottle in "Run For Your Ed" three seasons later.
"A Glass of Warm Ed" has a "blink and you'll miss it" nod to a previous episode, with the "En-o-Gee drink" stand from "Over Your Ed" making a reappearance.
The events of "Run For Your Ed" are a result of Ed's sleepwalking problem from "A Glass of Warm Ed" popping up again, which unwittingly results in the Kankers precious Ship in a Bottle getting stolen, inciting their wrath.
"Dueling Eds" features the giant piggy bank from "Fa-La-La-La-Ed", rotting in the junkyard.
"Three Squares and an Ed" features cameos of the Newspaper Machine and the Elevator Boots from "Read All About Ed" and "A Pinch to Grow An Ed".
The clubhouse from "Virt-Ed-Go" makes a sudden reappearance as a refuge from Monster Ed in "The Day The Ed Stood Still". It's even still painted pink and says "Club Kanker". It doesn't last long against Edzilla, though.
The "Hive Bee Gone" overalls from "Pop Goes The Ed" reappear in "To Sir With Ed", with "Hive" crossed out and replaced with "Snake" as Ed and Edd think they're fighting a snake.
"My Fair Ed" references Ed tearing up Edd's screen-door in "Button Yer Ed".
Edd's steel guitar from "Avast Ye Eds" reappears in "Rambling Ed", "Brother, Can You Spare an Ed?" and "Out With the Old, In With the Ed".
In "May I Have This Ed?" Ed produces a "lucky cheese chunk" he calls Sheldon Jr., a reference to his lucky cheese chunk Sheldon from "Thick as an Ed".
This exchange from "Stuck in Ed", where Eddy convinces Jimmy to help him think up a scam, and Edd brings up the events of the episode "Ed in a Half-Shell":
Rolf's TV from an early episode pops up again as a plot device in one later episode.
"A Fistful of Ed" has Jimmy's snake tattoo from "Urban Ed" reappear. Eddy also makes reference to the episode where Eddy turned Jimmy into a sumo wrestler.
In "Fa La La La Ed", Rolf's Christmas present to Jonny is the yo-yo Ed traded to him for a sack of plums in "Keeping Up with the Eds".
Contrived Coincidence: In "Who, What, Where, Ed" (the Chain of Deals episode), the Eds need some clams but are having no luck. Just when they're about to give up, Jonny pops out of the sewer wearing SCUBA gear and holding a bucket full of clams. Edd remarks "That was convenient."
Cosmic Playthings: Edd's only explanation as to why the trio can't get free jawbreakers in the episode "Don't Rain on My Ed".
Could Have Avoided This Plot: Lampshaded by Edd at the end of "Eds Aggerate" when him with Ed and Eddy are stuck to cement for lying about breaking Kevin's window.
Edd: This all could have been avoided, if we'd just tell the truth.
The Eds constantly attempt (and often fail) to make money by scamming the kids - although they never think of getting a regular allowance from their parents nor doing chores to get the money.
Ed's dad is too busy, Edd doesn't get compensated for chores, and Eddy...uh...probably wants more money.
Edd is also capable of building several cardboard technologies and the trio never think to just sell them. Granted, they do fall apart a lot.
They did try to sell his Thingamajig invention once, sort of, but then Captain Melonhead showed up.
Darker and Edgier: The Movie, due to the kids' obsession with hunting the Eds down and actually wanting to kill them. Plus, The Reveal that Eddy's brother is physically abusive. Contains a ton of spoilers!
Kevin and the kids get an episode to themselves: "See No Ed".
It gets so weird for the cast that they start searching for the Eds. Some are worried, some are curious, and Kevin is just getting increasingly paranoid that the Eds are up to something. Turns out that the Eds were trying to set up a scam, but they couldn't find Ed's mask and glove (both of which had been found earlier by Jonny and Jimmy, respectively).
The movie easily doubles the characterization and depth of relationships for the cast, but Kevin and Nazz' relationship especially.
I Am Curious Ed focuses on Jimmy and Sarah instead of the Eds.
Edd, who becomes increasingly snarkier after the first season.
Eddy also has his moments—Kevin too.
Digging to China: "For Your Ed Only" - Johnny hits the ground so hard he pops up in China. "Just like in the cartoons!"
Disaster Dominoes: The Movie begins with the aftermath of a presumably titanic set of these, which has left most of the Cul-De-Sac in ruins and the Eds fleeing for their lives.
"May I Have This Ed?" climaxes with this, accidentally set off by Nazz when she asks Double D to dance with her in front ofMarie. Within sixty seconds, the entire school building has been annihilated.
Disguised in Drag: Double D dresses up as a mermaid in "Tinker Ed" to try to convince Jimmy that fairytales are real.
Jimmy at the end of "Ed Overboard".
A hilarious instance occurs in "In Like Ed", (in which the Eds believe that Jimmy's birthday party is actually a secret spy meeting). Double D infiltrates the party disguised as Nazz, and begins analyzing the food by inserting them into a machine...hidden in his pants. Later, Eddy helps with the analysis by shoving in a piece of cake, only to realize that he had just stuffed it into the REAL Nazz's pants.
To be fair, most of what the neighborhood kids do to the Eds is this, since they're causing the Eds insane amounts of physical pain and probably psychological scaring...over 25 cents and maybe a few scrapes.
Then there's the fact that all 3 Eds tend to get punished for what only 1 or at most 2 of the other Eds were responsible for. A good example is the Halloween episode where Ed beats up all the other kids due to horror movie provoked hallucinations and the other 2 are beaten up for it while Ed gets off scot free.
Perhaps the most egregious example is the episode "If It Smells Like an Ed" where Jimmy framed the Eds for conspiracies they did not commit...because Eddy, and only Eddy, gave him a wedgie. Sure one could say that it was understandable for Jimmy to get retribution for his humiliation, but Ed and Edd have done nothing at all to deserve this.
Does This Remind You of Anything?: In one episode, Double D gets hold of a boomerang and begins to sweat because of how hot it is outside, and then proceeds to strip pretty sensually for a kid's show, clinging on to a pole, and shakes off his pants with no shame whatsoever. This stops when Eddy yells at him and takes the boomerang away from him.
Domestic Abuse: After over 100 episodes, Eddy's Brother is revealed to be a Jerkass who beats Eddy to a pulp when he asks for a little protection from the neighborhood kids. This turns nasty when you realize that Eddy is only around 12, his brother has to be in his 20s, and he probably practiced the same level of abuse for the entire time he lived with their parents.
Notable examples: "If It Smells Like An Ed", the Halloween special and the Christmas special "Jingle Jingle Jangle".
In general, the only episodes that ended with the Eds not getting beaten up, getting their scam ruined, or otherwise humiliated are "A Glass of Warm Ed", "Rent-A-Ed" (the scams got ruined, but the Eds got a happy ending anyways), "Run For Your Ed", "The Day the Ed Stood Still", "A Fistful of Ed", "Dear Ed", "The Good Ol Ed", "Cleanliness is Next to Edliness", "May I Have This Ed?", the Valentine's Day special, and The Movie.
Dreadful Musician: In "Pain in the Ed", Ed is forced to take violin lessons, and is so bad at it that it causes the bark to peel off trees, and Kevin's bike to crumple up.
The episode "Rock-a-Bye Ed" opens with Ed having a nightmare of Johnny 2x4 as his mother ripping off his mouth and lowering him into the "Kanker pit" for annoying Sarah. This sets up the conflict of the episode, in which Ed develops a crippling fear of Johnny.
The special "The Eds Are Coming" opens with Jimmy having a dream of living in a sunshine-and-rainbows wonderland before it turns into a nightmare when aliens attack.
*Drool* Hello: Monster Ed pulls this on Eddy in "The Day The Ed Stood Still".
Dude Looks Like a Lady: It can be pretty easy to mistake Double D for a girl—his high pitched voice doesn't help.
Dude Magnet: Nazz is this full-stop. Rolf and Jimmy are the only male characters who don't have a crush on Nazz.
Dumb Blonde: May and, to a lesser extent, Nazz (especially in later episodes).
Dumb Is Good: Mostly played straight. Ed and Jonny are Kindhearted Simpletons, Nazz is a bit ditzy, but very sweet, and May is the dumbest Kanker and probably the most innocent and least cruel of the three. Subverted however with Edd who is a genius and easily the nicest character on the show.
Dumb Muscle: Edd is outwardly the smartest and also one of the weakest (along with Jimmy). Ed, the least intelligent member of the cast, can lift a whole house before he's out of diapers.
Dungeon Bypass: In "They Call Him Mr. Ed", Ed simply runs in a straight line through all the walls of Double D's "maze of inevitable despair" ("catchy, isn't it?") to get to a box of Chunky Puffs.
Edd: Excuse me, Ed. Not that you'd understand the geometry involved in such an endeavor, but that isn't how you go through a maze!
The early shorts had much cruder animation, Double D was much more relaxed than he is later on, Eddy is more of a heckler than a flat out greedy jerk, and Ed wasn't stupid so much as he was an absentminded 12-year-old. Also, there was the first episode, where they actually did get their jawbreakers—sort of.
Edd was actually referred to by his real name causally at times in the Pilot, rather than Double D.
The Kankers' introduction episode "Nagged to Ed" portrayed the trio in a much more sympathetic light compared to the rest of the series. While they were still introduced as the creepy Abhorrent Admirers they have always been, (Removing the Eds clothing while replacing them with their dad's robes, drawing pictures of them marrying their respective Ed, etc.), they were shown to be quite hospitable and tried to impress the Eds into liking them, instead of forcing themselves onto them. The Eds were even shown in a slightly negative way by taking advantage of their hospitality. Also, they weren't bullies until later on.
Edd used to have a crush on Sarah in The Ed-Touchables. As the show progressed, the feelings got reversed.
Ed was a lot less terrified of Sarah. In Pop Goes the Ed, he rather smugly defied her when she ordered him to leave the pool and he would try to calm her down whenever she misbehaved, like in To Sir With Ed.
Ed and Double D were a lot meaner and intruding on par with Eddy's personality in the older episodes (although Double D himself was always a neat freak). For instance, in "Ed Touchables" and "Pop Goes the Ed", both Ed and Double D scared Jonny, while in later episodes, they're rather friendly.
The title card is done differently in Season 1. The tune is completely different and for the first few episodes, the text is in a straight line as opposed to artsy.
Earn Your Happy Ending: After "130 episodes, four specials and a movie!" of physical, mental and social humiliation, the series ends with the Eds finally being forgiven and accepted as friends by the rest of cul-de-sac as well as finally getting jawbreakers.
Easily Impressed: Between all the kids in the culd-de-sac, Ed, Rolf, and Jonny are definitely the easiest to enrapture. In the cases of Rolf and Jonny, this makes them particularly easy to rope into a scam.
Election Day Episode: One episode has the kids hold an election for "king of the cul-de-sac", with Plank and Eddy as the main candidates. Plank won in a landslide.
Embarrassing Middle Name: Eddy's middle name is Skipper, and Double D's is Marion. Also revealed in one other episode that Ed's middle name is Horace, even though he has the least embarrassing middle name of the trio.
Enemy Mine/Go-Karting with Bowser: Before the ending movie, the Eds and the other kids do team up with each other from time to time, most notably in the alien invasion special. The kids can be downright friendly when they aren't be ripped off or pranked.
Epic Fail: Several of the Eds' scams, most notably, the Ancient Egypt scam; Edd is unable to descipher Ed's 'heiroglyphs, their 'mummy' walks in late for his dramatic reveal, and the sand ends up making him sneeze so hard he blows the entire sphinx (Made entirely from cardboard boxes) into the sky. The episode "Once Bitten, Twice Ed" cranks this trope Up to Eleven after Jonny keeps ruining the arcade and Eddy insist on running the arcade even after people saw through the scam.
In "Pain in the Ed", Eddy's armpit hair (made of purple carpet) is so obviously fake that even ED sees right through it.
Eddy: Hey Ed! Check out these pits!
Ed: Nice carpet, Eddy!
"Oath to an Ed" sees the Eds trying - and failing miserably - to earn a badge to become Urban Rangers, which involves such mundane tasks as microwaving a burrito, changing a roll of toilet paper, and laying in a hammock. What really sells it is the end of the episode, when it's revealed that Plank succeeded where the Eds failed.
Even the Subtitler Is Stumped: The subtitler for The Movie's premiere broadcast in the United States registered everything Rolf says as (unintelligible)...even though the things he was saying were very clear.
Evil Versus Evil: Although it's debatable how "evil" he is, Eddy may be a sneaky con artist who will stoop to any measure to get what he wants, but the kids he's scamming aren't exactly saints either; also, Eddy whenever he encounters the Kankers, who want to love them... whether they like it or not: so technically, its the Eds' evil (scamming the kids for money) versus the other kids' evil (being unnecessarily cruel to the Eds and themselves most of the time) versus the Kankers' evil (terrifying the local populace because they seem to Stockholming their crushes is an acceptable form of courtship).
Evil Plan: Jimmy, of all people, in "If It Smells Like an Ed". After Eddy (and ONLY Eddy) gave Jimmy a wedgie, everyone else laughs at him. To get revenge, Jimmy then targets all three Eds by framing them for stealing several neighborhood items. Unfortunately, the Eds can't clear their name and are forced to choose between getting beaten up by the other kids or getting attacked by the Kanker Sisters. They choose option A as the Lesser of Two Evils, and end up getting both options because Jimmy didn't think they suffered enough.
On the bright side, karma catches up with him, depending on whether you count slipping on a banana peel full punishment (Being Jimmy, that probably counts as a serious casualty).
Ed, when around his friends and especially around Sarah, probably because he's too stupid and seems just happy to be an obedient follower. He doesn't even mind being abused by his younger sister or treated like an object, despite being extremely strong. Not including "Little Ed Blue", he only stands up to Sarah once, because Eddy told him to, and immediately feels guilty about this when Sarah starts crying.
Edd has shades of this in the first season, but becomes more argumentative later on, especially when it comes to Eddy and his scams.
Failure Is the Only Option: Almost of the Eds' scams and efforts backfire in some form or another. Even if they get away with it, their rewards are usually either lost or destroyed.
In "Don't Rain on My Ed", their efforts to get to the candy store before Customer Appreciation Day ends are frustrated in increasingly arbitrary and silly ways, finally culminating in a fierce thunderstorm and an apparently random "chicken drive" blocking their path to the candy store.
One episode, during which they turn Jonny's house into a sauna, seemed to end with them escaping and keeping the money. They get away by breaking a fire hydrant and riding the geyser-like jet of water into the air, while still holding on to the money. Even Kevin comments "Hey, the Ed-weirdo brothers aren't too bad!" as the episode ends.
A comic version of the pilot episode ended as the Eds were running off to purchase jawbreakers with the money they gained - the actual show continued to them eating the jawbreakers, only for Jonny in a tire to run into them and make them lose them.
In Ed's case, it got so extreme that the writers had to reverse the trend, and made him a little smarter again. At least, he regained the ability to speak in coherent sentences. Similarly, Eddy got meaner and meaner, then got nicer again in the movie and later on in Season 5.
A showcase of Flanderization within the show can be found in the episode "All Eds Are Off", where the Eds, Kevin, Rolf and Jonny place a bet on who can keep off their most annoying habits. Their habits are what their Flanderization culminated into, with the exception of Jonny who has to stop listening to Plank, which is his whole character.
In-universe Flanderization happens in the "Truth or Dare" episode where the Eds each act like Flanderized versions of each other. Ed acts like Eddy, Double D acts like Ed, and Eddy acts like Double D. Ed comments on this at one point:
Edd:(imitating Ed) Uh-oh, a fence. (deliberately walks into it and falls over) Gravy! Ed: Aw, come on Double D, I don't say "gravy" all the time! Edd: Buttered toast, then!
Forceful Kiss: Done frequently by the Kankers to the Eds. For instance, in the ending of The Movie, the Kankers dragged Eddy's unconscious brother into his mobile home to give him "mouth to mouth."
Then there's the canon kiss between Edd and Eddy in "Your Ed Here".
In one episode where Eddy made the claim his brother was coming back, he believed doing this would give him some respect, only for Edd to mention after the first few people that it was fear they were all showing, not respect, and when Sarah and Jimmy (disguised as Eddy's brother) showed up at his doorstep, Eddy looked about ready to wet his pants from fear. This is the earliest sign we've seen that Eddy's brother isn't the awesome badass he's been made to be.
A very easy bit to miss: towards the end of "An Ed is Born", after "showing" his brother how cool he is, Eddy makes the comment "No more beatin' up little Eddy, eh, big brother?" Once you've seen the movie, this line sticks out like a sore thumb.
Friend or Idol Decision: In "Don't Rain on My Ed" the Eds rush to get free jawbreakers from their local candy store. Just a stone's throw from reaching it, they're beset by an out of the blue storm and a chicken drive (don't ask). Edd is swept in the flood of poultry and begs Eddy, who managed to get out, for help. In a rare subverted case, Eddy goes for the jawbreakers, but the store closes and he loses his "idol" anyway.
Friendship Song: "Friends Are There To Help You" is a humorous kids song about how no matter what happens friends will be there for you.
In one episode, Ed drinks an experimental and highly volatile soda Edd created. Edd tells him to stay completely still so he doesn't set off the mixture, but Eddy forces him to start moving around by tickling his belly with a feather.
In "From Here to Ed", Eddy tries to get revenge on Kevin for ruining one of his scams, and one scheme he has is hitting him over the head with Ed's rotting, moldy lunch bag. Eddy tells Double D to hit him since he's the only one of the three that wouldn't look suspicious approaching Kevin. When he refuses, Eddy and Ed tickle him until he's right behind Kevin.
One episode has Ed and Edd hanging from a set of monkey bars, which Eddy is too short to reach up and grab like they did. When he protests to their assistance and poking fun at his height, they tickle him under his arms until he falls off.
In the episode "Stop, Look, and Ed" where Eddy encourages all the kids in the culdesac to break and disregard the rules, there's a scene when Ed tickles Kevin.
Funny Background Event: In "Fa La La La Ed", while Jimmy is complaining to Sarah about the pain of smashing his piggy bank, we see Ed falling over as he tries to prop up some Christmas lights.
In "Look Before You Ed," while Edd and Jimmy are covered in snow in the foreground, Eddy and Ed steal Kevin's snowboard in the background.
In "May I Have this Ed", while Edd is talking in the foreground, Ed and Jonny are "dancing" together in the background.
In this scene, while Eddy and Double D talk, Ed just stands on his head in the background, using only his eyebrow to move forward. Really, it has to be seen to be believed.
Genre Savvy: In "The Eds are Coming, The Eds are Coming" (The CN Invaded special), the implication of an actual alien invasion leads Double D to research Ed's comic books to produce countermeasures against it.
Ed: (matter-of-fact) I forgot to wear underwear, guys.
Grand Finale: The Movie, which even breaks the fourth wall to make it clear to the viewers that it is the end.
Gravity Is a Harsh Mistress: As the show is full of Toon Physics, this pops up every now and then. A notable example is in "Mirror, Mirror, on the Ed", where Ed and Eddy don't realize they stepped off a cliff before they look down.
The Great Whodini: Eddy, upon aquiring Double D's hypno-wheel, proclaims himself to be "The Great Eddy-dini".
The Eds swindle the other kids out of their hard-earned, that is true. However, Ed is a Kindhearted Simpleton and Edd is a Lovable Nerd who are mostly just egged on by Eddy, and while he himself is a Jerkass at times, in the movie it is shown that he has a hugeFreudian Excuse.
Sarah is an abusive spoiled brat, but she shows huge concern for Jimmy, and she has a soft-spot for Edd as well—it's also been shown at times that she truly does care about her brother.
Kevin is a bullying Jerk Jock to the Eds, and Jimmy and Jonny, but much of his paranoia and hatred of the Eds is brought about by their scams.
Eddy does this to Ed when he learns that the lump hid Eddy's magazines and the box that they came in in different places.
Eddy gets one in "An Ed is Born" when Kevin loops Eddy's underwear elastic to the back of his bike and speeds off. Eddy's voice quickly raises in pitch while he tries to hang on and play it cool for the camera.
Jimmy also becomes a victim of this in one episode as seen here.
